+As suggested by Keith in FLAG_PURE_NOT allows for expressions like:\r
+\r
+  notmuch search NOT tag:inbox\r
+\r
+Note that this way a search like:\r
+\r
+  notmuch search foobar NOT tag:inbox\r
+\r
+should not be written instead:\r
+\r
+  notmuch search foobar AND NOT tag:inbox\r
+\r
+In my opinion, the latter feels more natural and is somewhat more explicit.\r
+It gives a better clue of what the search is about instead of assuming that\r
+an implicit AND operator is there.\r
